Very cool. No surprise when I saw Ben Eater acknowledgement at the bottom. I'd humbly suggest including the CAD (KiCad?) files to go along with the gerbers.

The Minitel can be used as a modem too, albeit a cumbersome and very slow one: 1200bps down, 75bps up. Bps as in bits per second. That’s how I connected to bbses and nntp before I finally got a 2400bps real modem.

Nice project, and how far we’ve come !
